Genetic, Environmental Factors Identified in Social Networks > Yale School of Public Health | Yale School of Public Health:
Jason M. Fletcher, Ph.D., associate professor in the Department of Health Policy and Management, and colleagues used data on social networks and genetics within middle and high school settings to determine how gene-environment interactions influence complex relationships such as friendships.
The analysis found that specific genetic factors in a region of a receptor gene known as DRD2 predict friendship formation in schools, suggesting that an individual’s basic “social” choices are influenced, at least in part, by biological and genetic underpinnings.
